Hello,
After upgrading Zabbix (from 4.4 to 6.4), the ping to some of the sites I previously monitored (both DNS and IP) stopped working. Oddly enough, I can't even ping these sites directly from the server—I mean directly from the VM via SSH. I can ping other random addresses; it seems that this issue is really only affecting addresses that I monitored before the upgrade.
I don't even know where to start debugging in this case. In the logs, I only have a few notes about issues with SNMP in combination with my Mikrotik, which I plan to address later.
